How A Supercomputer Named Dr. Crusher Perfected Cancer Treatments For 21 Patients
Sequencing tumor genes and then selecting treatments that target certain mutations is routine in the treatment of several tumor types, including breast and lung cancer. But it’s not common practice for treating hematological malignancies like multiple myeloma, even though oncologists who treat those diseases are well aware that each patient’s cancer has unique characteristics that may make it more or less responsive to certain targeted treatments.
Oncologist Samir Parekh and his colleagues at the Mount Sinai Icahn School of Medicine in New York wanted to change the treatment paradigm in multiple myeloma. So they developed a system that uses an algorithm to match up multiple myeloma patients with drugs that are already on the market to treat other cancers. They tried the resulting recommendations in a group of 21 patients with treatment-resistant multiple myeloma and got positive results in all but five—a response rate that’s so high Parekh believes the idea could be extended to many other cancers.

Google’s DeepMind AI can accurately detect 50 types of eye disease just by looking at scans
DeepMind published on Monday the results of joint research with Moorfields Eye Hospital, a renowned centre for treating eye conditions in London, in Nature Medicine. The company said its AI was as accurate as expert clinicians when it came to detecting diseases, such as diabetic eye disease and macular degeneration. It could also recommend the best course of action for patients and suggest which needed urgent care.
- Google’s artificial intelligence company DeepMind has published “really significant” research showing its algorithm can identify around 50 eye diseases by looking at retinal eye scans.
- DeepMind said its AI was as good as expert clinicians, and that it could help prevent people from losing their sight.
- DeepMind has been criticised for its practices around medical data, but cofounder Mustafa Suleyman said all the information in this research project was anonymised.
- The company plans to hand the technology over for free to NHS hospitals for five years, provided it passes the next phase of research.
- Google’s artificial intelligence company, DeepMind, has developed an AI which can successfully detect more than 50 types of eye disease just by looking at 3D retinal scans.

CloudQuant Thoughts… After the recent well-documented failure of Watson in the area of Cancer diagnosis (worse than failure – recommending treatment regimes that could be harmful to the patient) it was good to read these stories of ML successes in medicine including one for their competition – Google’s DeepMind. Again, ML is impressive when used more as a leverage to human ability. Honing in on problem areas and making suggestions seems to be the current ideal step for a lot of ML and AI improvements in workflow.
Ideas on how AI should Improve Our Daily Lives
In most every example of Artificial Intelligence (AI) in business, there is a chat bot or robot or algorithm that attempts to replace a human. We surely will see replacement via AI, but augmentation is also a value approach. In augmentation, a AI process considers various options and provides the human with improved decision options, based on some deeper consideration or at least with more complexity and optionality involved. There are many things we currently do that are doing regularly that are often conducted with limited consideration of options or a poor consideration of complexity. The penalty we experience is in cost, quality of life, and loss of time. Here are some things, that I think, merit an AI process for continued improvement in everyday life.
- Daily Dynamic Scheduling
- Achieving Best Pricing on Regular Purchases
- Deep (and On-going) Searching
- Cash Management

CloudQuant Thoughts… These suggestions continue the idea that ML and AI are going to be best used, initially, as leverage to human thought and decision-making processes. I tried to find a video of Apple from late 80’s early 90’s demonstrating a Search that they had called “AN AVATAR” who would continue to search for new information on the “World Wide Network” on subjects that you found interesting. Having someone shop for you can save you hours of your precious time for a very small cost. If we throw away 40% of our food every year, maybe eating out is not such a bad idea.
Android Pie: Google Launches New Artificial Intelligence-Powered OS
Google on Tuesday rolled out Android Pie, its highly-anticipated mobile phone operating system. This OS’ major updates focus is on artificial intelligence, which will allow the system to “learn” from the user and customise the Android experience.
With the Android Pie update, the search engine giant has promised that the phone would become more and more tailored and customised with the user’s behaviour and usage. “We’ve built Android 9 to learn from you — and work better for you — the more you use it,” said Google in an official statement.

CloudQuant Thoughts… It is a pleasure to see companies like Google using AI to improve the user interface. I am always reminded of Palm OS’s three clicks rule (developed from the 80/20 rule) that all information should, wherever possible, be reachable within three clicks maximum.
As we continue to develop our CloudQuant web service, we are always trying to think of how to get the most important data to our users in the smallest number of steps. As an example, today we roll out extra features relating to viewing the best and worst trades taken by your backtests. We now sort all backtest days by the absolute PnL and within each date all trades are, by default, sorted by absolute Gross Profit, so now you can quickly access your best and worst days and trades. We have also added keyboard shortcut keys to allow our users to quickly scan through the charts for their trades. See the CloudQuant forum post for more information.

Delayed impact of fair machine learning
“Delayed impact of fair machine learning” won a best paper award at ICML this year. It’s not an easy read (at least it wasn’t for me), but fortunately it’s possible to appreciate the main results without following all of the proof details. The central question is how to ensure fair treatment across demographic groups in a population when using a score-based machine learning model to decide who gets an opportunity (e.g. is offered a loan) and who doesn’t. Most recently we looked at the equal opportunity and equalized odds models.

K-Means Clustering, Creating a Simple Trading Rule for Smoother Returns
What is K-means clustering? K-means is an iterative refinement algorithm that attempts to put each data point into a group or cluster. The algorithm starts with initial estimates for the K centroids (centers of the mentioned groups) and continues moving the centroids around the data points until it has minimized the total distance between the data points and their nearest centroid. The user will generally specify K which is the number of centroids (groups). The algorithm can be thought of in two repetitive steps:
- Data assignment – Each centroid defines one of the clusters. In this step, each data point is assigned to one of the centroids or clusters. Assignment is typically done based on Euclidean distance.
- Centroid Update – Centroids are then recomputed or moved. This is done by taking the mean of all the data points assigned to that centroid’s cluster

Deploying Machine Learning Models is Hard, But It Doesn’t Have to Be
With free, open source tools like Anaconda Distribution, it has never been easier for individual data scientists to analyze data and build machine learning models on their laptops.
So why does deriving actual business value from machine learning remain elusive for many organizations?
Because while it’s easy for data scientists to build powerful models on their laptops with tools like conda and TensorFlow, business value comes from deploying machine learning models into production. Only in production can a deployed model actually serve the business. And unfortunately, the path to production remains difficult for many companies.

Why Is Auto-Keras Gaining Such Popularity?
Auto Keras is the new open-source neural network library built for automated machine learning. This is built upon Keras where one with less knowledge about machine learning can make use of this library to build neural networks. This library makes the job easy with the help of automated search for hyperparameter selection and finding the optimized values. Let us dive into how to get started with it:
The automated machine learning packages are gaining popularity because of their easy-to-implement technique. A person from a non-AI background or one who has very less machine learning knowledge can build and train neural network within a few lines of code. Let us see how it can be installed.

Robotic Process Automation (RPA) And Artificial Intelligence Don’t Have Many Things In Common
Researchers across the globe are trying to inculcate technologies such as robotics and AI in their workflows to optimise and automate them. In such processes, Robotic Process Automation (RPA) is one of the most popular terminologies and is often sought-after for handling operational tasks with least manual intervention. In other terms, it is a software that automates low-level tasks.
However, the two terminologies AI & RPA are used interchangeably. It is important to realise that both RPA and AI facilitate a common goal of Intelligent Automation. While RPA is often picturized as a software robot mimicking human actions, AI is the simulation of human intelligence by machines. In this article, we list down 5 major differences between the RPA & AI.

Ultimate guide to handle Big Datasets for Machine Learning using Dask (in Python)
Have you ever tried working with a large dataset on a 4GB RAM machine? It starts heating up while doing simplest of machine learning tasks? This is a common problem data scientists face when working with restricted computational resources. When I started my data science journey using python, I almost immediately realized that the existing libraries have certain limitations when it comes to handling large datasets. Pandas and Numpy are great libraries but they are not always computationally efficient, especially when there are GBs of data to manipulate. So what can you do to get around this obstacle? This is where Dask weaves its magic! It works with Pandas dataframes and Numpy data structures to help you perform data wrangling and model building using large datasets on not-so-powerful machines. Once you start using Dask, you won’t look back.
In this article, we will look at what Dask is, how it works, and how you can use it for working on large datasets. We will also take up a dataset and put Dask to good use. Let’s begin!

Artificial intelligence platform launches to tackle financial crime
As financial crime becomes increasingly sophisticated, a new AI tool has been developed to take on fraudsters, minimize the risks of human error and ensure regulatory compliance.
Technology and consulting services company Mindtree has launched an artificial intelligence and machine learning tool designed to help banks improve their ability to detect financial crimes and enhance reconciliation management. The service is powered by a machine-learning platform developed by predictive analytics specialist Tookitaki.
The launch comes as banks and other financial institutions come under pressure from the increasing sophistication of financial crimes worldwide and ever-more complex regulations requiring strict operating and reporting standards. Because manually detecting money laundering, dealing with false alarms and fragmented reconciliation processes can be costly and time-consuming, there is a growing need for financial institutions to automate many of these processes. Additional benefits of automation include the reduction of errors and quicker response times to incidents.

A NLP Guide to Text Classification using Conditional Random Fields
The amount of text data being generated in the world is staggering. Google processes more than 40,000 searches EVERY second! According to a Forbes report, every single minute we send 16 million text messages and post 510,00 comments on Facebook. For a layman, it is difficult to even grasp the sheer magnitude of data out there?
News sites and other online media alone generate tons of text content on an hourly basis. Analyzing patterns in that data can become daunting if you don’t have the right tools. Here we will discuss one such approach, using entity recognition, called Conditional Random Fields (CRF). This article explains the concept and python implementation of conditional random fields on a self-annotated dataset. This is a really fun concept and I’m sure you’ll enjoy taking this ride with me!

College Football – Who’s a Fan?
With the college football season about to begin, it is worth a look to see how the teams stack-up, not based on rankings, but based on fan loyalty. Big Data and Data Visualization help us with this and lead to some interesting insights. College football also offers us a great opportunity to look at the Big Data of fandom and the business of college football and even that of universities.
Building on my post that looked at NFL fan allegiance by location, I thought looking at some data visualization of college football allegiance would tell us a bit about who roots for which team and a bit more about how Big Data, Data Science, and data visualization are helping us understand complex problems in life and business.

Deep Learning in a “Mobile Phone” Environment
Building deep learning models that can execute on mobile runtimes is a very active area of research in the artificial intelligence(AI) space. After all, mobile devices are a significant source of information and host of computations in the modern technology ecosystems. Among the deep learning techniques that have been trying to adapt to the mobile world, none is more relevant than convolutional neural networks(CNNs) given that they are a foundational block to image analysis methods which can unlock the door to many new scenarios for mobile apps.
Google has been among the players leading the charge in the mobile deep learning space with research like Federated Learning or frameworks like TensorFlow Lite. Recently, researchers from the Google Brain team published a paper introducing MNasNet, a new method for designing CNN models that can effectively execute on mobile devices.

Comparing Generative Adversarial Network (GAN) to Encoder Decoder Architecture Is Like Comparing Apples To Oranges
Since the deep learning boom has started, numerous researchers have started building many architectures around neural networks. It is often speculated that the neural networks are inspired by neurons and their networks in the brain. Computational algorithms often mimic and copy these biological structures. But there is yet a lot to be discovered about how the brain actually works.
Neuroscience is nowhere close to solving the mystery of the brain. That is why artificial intelligence scientists have to come up with many neural network architectures to solve different tasks. Two of the main families of neural network architecture are encoder-decoder architecture and the Generative Adversarial Network (GAN).

Kroger inks Ocado grocery delivery deal to battle Amazon threat
What do food, A.I., and flight control have in common? Well, nothing. Unless you’re the U.K. online food retailer Ocado Group. This canny company uses A.I.-programmed flying robots to coordinate shopping basket fills in their depots, which shaves untold hours and operating costs off of the overheads and has seen its stock rocket in value.
U.S. supermarket chain Kroger Co (KR.N) struck a deal with British online grocer Ocado (OCDO.L) to ratchet up its delivery business with the construction of robotically operated warehouses, upping the ante in the battle with Amazon.com Inc (AMZN.O) and sending Ocado shares rocketing. The U.S. grocery industry is dominated by Walmart Inc (WMT.N) and Kroger but has been in upheaval since last summer, when Amazon’s $13.7 billion deal for Whole Foods sent supermarkets scrambling to match the online retailer on home delivery. The Kroger deal announced on Thursday is Ocado’s first in the United States and the British company’s fourth major agreement with retailers in six months.
A new system of grocery order picking is heading to North American shores courtesy of new deal being drawn up by an online grocer across the pond and one of the biggest retailers in the U.S. While this doesn’t sound like an obvious investment choice for domestic stock lovers, there may well be some upside in the venture.
